Late blight,caused by Phytophthora infestans(Mont.)de Bary,is one of the most devastating diseases in potato production at present.Understanding whether or not there is A2 mating type of P.infestans in Heilongjiang is helpful for drafting a strategy for late blight control.Samples of potato late blight were collected from the various areas of Daxinganling,Nenjiang,Nehe,Keshan,Hailun,Suiling,Suihua,Bayan,Hulan,Harbin,Shuangcheng,Linkou,and Wangkui for isolation and purification in this research.Totally,124 P.infestans isolates were obtained and then tested for their mating type using standard strains and dual culture method.The results indicated that all of 124 isolates were of A1 mating type,and no A2 mating type was detected in Heilongjiang province.
